Mitakon Zhongyi Speedmaster 85mm f/1.2 lens officially announced

The Mitakon Zhongyi Speedmaster 85mm f/1.2 is a ultra-fast portrait lens that delivers unbelievable optical performance. A maximum aperture of f/1.2 makes it extremely convenient for shooting without flash in low light conditions. Designed for the use of full frame cameras, the large aperture also provides fine control over depth of field for fascinating portrait photography. The truly circular aperture creates a shallow depth-of-field that brings attention to the subject and blurs the background, which is critical for portraits. The lens incorporates 9 elements in 6 groups with 2 pieces of Extra-low Dispersion elements & 4 pieces of High Refractive Index elements. This helps reducing aberrations and maintain excellent sharpness even at f/1.2. . Manual focus design and a click-less, silent aperture ring promote smooth handling and are especially well-suited to video applications. The lens is built of metallic enclosure with additional protective processing, which gives extra durability and aesthetic.
